Safely Store Idle Pallets to Minimize Risk

Stockpiling idle storage pallets can present a serious fire hazard. Take steps to store pallets responsibly and minimize risk.
Many businesses that store and ship goods or supplies typically use pallets at their facility. Various amounts of these pallets are often stored in areas throughout the building when not in use. However, stockpiling them could present a serious fire hazard. Because of their dried-out condition, high rate of heat release, and overall arrangement, even a small ignition source could spark a quickly spreading fire that may cause a devastating loss. Fortunately, you can help reduce this risk by moving idle pallets outside and away from your building, or by strictly limiting storage arrangements and employing an appropriate automatic sprinkler system.

General storage tips
When not in use, pallets should be stored outdoors if possible They should be stacked in a flat manner and arranged in stable piles in an orderly fashion. If outdoor space is not available, pallet storage areas should be separated from other storage areas. The National Fire Protection Association (NFPA) Fire Standard states that pallet storage arrangements should be either outside, in a detached structure, or in a properly sprinklered facility.

Designate an outdoor storage area

When storing Idle pallet stacks outdoors they should not exceed 15 feet in height or cover an area greater than 400 square feet.  Pallets can be stored outdoors as per the following table as per NFPA.
 
Indoor storage of wood pallets
If your facility has indoor storage of pallets, whether temporary or long term, your building should be equipped with a properly designed automatic sprinkler system. The design of the sprinkler system is dependent on several variables including pallet stack height, building ceiling height, and water flow capacities. In addition, rack storage should not be permitted unless protected by an Early Suppression Fast Response (ESFR) sprinkler system, in accordance with NFPA 13, Standard for the Installation of Sprinkler Systems.

Plastic pallets may be a greater hazard
Plastic pallets other than non-expanded polyethylene solid deck pallets can present an even greater fire hazard than wood pallets. See NFPA 13 for specifics of protection.
